Extensions mean ten-spin additions earned after each fourth fisherman in the measured Standard feature. Eighteen of fifty purchased features received at least one; initial awards of fifteen or twenty spins are starting grants, not extensions. Super uses a different three-fisherman threshold and was not sampled.

One ticket equals 100 ordinary stakes. Natural bonuses occurred once per 147 paid rounds in this sample. Stakes multiplied by this interval measure gross wagering, not the net cost of obtaining a bonus. Purchase returns above include the complete purchased round and are divided by the ticket price.

How it plays

7 rules screens from the game

The money fish and the fishing equipment do different jobs on this five-reel, three-row board. Boats, rods, dragonflies, tackle boxes and card symbols form left-anchored combinations across ten paylines; boats begin paying with a pair. Money fish instead carry values from 0.2x to 50x the total stake, and an occasional base-game collection can apply individual multipliers reaching 50x.

Three scatters award ten free spins, four award fifteen and five award twenty. A two-scatter base screen can gain another scatter through a reel respin or an octopus transformation. Fishermen appear as wilds during the feature, replacing regular paying symbols but neither scatters nor money fish.

Each fisherman gathers the visible fish, using the multiplier already attached to each occupied position. Fish appearances raise those position multipliers even without a fisherman; new fish bring new money values on subsequent spins. Every fourth collected fisherman grants another ten spins in the standard feature, and random additions or reel changes can bring fish and fishermen together.

Two purchases are offered: Standard at 100x the stake and Super at 300x. Super reduces the extension threshold to three fishermen; only Standard purchases enter the fifty-ticket sample here. Ante changes the ordinary ten-credit wager to fifteen credits and increases the natural-feature chance.

The build specifies medium volatility and a 5,000x win ceiling, with ordinary stakes from USD 0.10 through USD 250. Its rules print USD 375 as the maximum including Ante; the normal-mode bet panel confirms USD 250. Theoretical RTP is 96.07% in normal play, 96.06% with Ante, 96.08% for Standard purchases and 96.09% for Super purchases.

Verdict

The grid remembers positions, not fish values

Round 1956 began with three free spins that paid nothing. Two fish visits had nevertheless raised one position from 1x to 3x; when a fresh USD 30 fish appeared there on spin four, its contribution was USD 90. That first fisherman gathered USD 154 from fish whose unmultiplied values totalled USD 92. A second collection added USD 1.60, leaving the ten-spin feature at USD 155.60 without an extension.

This unpaid preparation appeared throughout the ordinary sample: 647 natural-feature screens contained fish without a collector. Position growth did not itself credit the balance, and the fish showing on those screens were not stored for later payment. Actual natural-feature collection supplied USD 9,466.80; line awards added USD 160.80 to complete the USD 9,627.60 bonus-only total.

Standard purchases recovered USD 5,890.60 from USD 10,000 spent, with a mean recovery of 0.58906x the ticket and a median of 0.401x, or USD 80.20. Forty-two of the fifty tickets failed to recover their USD 200 price, while the largest paid USD 588.40. That best purchase lasted forty spins, but its extended grid still returned only 2.942x the ticket price: counting spins or accumulating multipliers does not describe the final recovery.

Measured upsides
  • Uncollected fish can improve a position multiplier for a later fish and fisherman combination.
  • Money collection also occurs in the base game: 190 such events returned USD 3,857.80 in the ordinary sample.
  • Standard and Super purchase modes state separate prices, RTP settings and collector thresholds.
Measured downsides
  • The Standard ticket median was USD 80.20 against a USD 200 outlay.
  • A higher position multiplier has no cash value until a fisherman collects a fish there.
  • The ordinary test ended USD 2,941.40 below its starting balance.
What the AI noticed during the run
  • A random base-game fish collection in ordinary round 443 paid USD 132.40 from USD 34.40 in unmultiplied fish values.
  • Ordinary round 3777 led the complete-round results at USD 737, including thirty free spins; the biggest individual screen occurred elsewhere, in round 4617, at USD 386.
  • Natural features started 68 times; 19 received an actual extension, and all 68 began with ten spins.
  • Sixty-seven successive zero-payout rounds ran from 846 to 912 before the streak ended.

FAQ

5 questions · answered from the log
Do fish without a fisherman still improve the multiplier grid?
Lab answer

Yes. In round 1956, fish on free spins two and three raised one position to 3x without paying anything. A new USD 30 fish on spin four then contributed USD 90 when the first fisherman arrived. The persistent element was the position multiplier, not the money printed on an earlier fish.

What separates the Standard and Super bonus purchases?
Lab answer

Standard costs 100x and awards ten extra spins per four collected fishermen. Super costs 300x and needs three fishermen for that extension. At USD 2, those prices are USD 200 and USD 600 respectively; all fifty measured purchases used Standard, so this review has no Super purchase distribution.

Did Standard tickets usually recover their price?
Lab answer

The median complete payout was USD 80.20, exactly 0.401x the USD 200 price. The mean was higher at 0.58906x, while 42 of 50 payouts remained below the purchase cost. Across the whole purchase sample, the deficit was USD 4,109.40.

Does 85.293% replace the stated 96.07% RTP?
Lab answer

The 85.293% result divides the ordinary sample return of USD 17,058.60 by USD 20,000 wagered. The rules state a theoretical normal-play setting of 96.07%; a finite run can finish above or below it. Purchased features are measured separately and do not enter that ordinary ratio.

Are the demo footage and the statistical rounds the same session?
Lab answer

No. The footage comes from another browser session at USD 2, using virtual USD credits. Both the ordinary statistical series and the fifty Standard purchases exclude that media play; the embedded demo also lets the ordinary stake be set to USD 2 with Ante off.
